The example assumed that there was always at least one TX and on RX
channel. Since that is not always true, this change checks for TX
and RX channels and only exucutes tests for what exists on the device.

For the burst ACK test, test_messages would send 3 packets. However,
that assumes that the underlying link is fast enough to send three
packets in time, and some devices are hard to operate without underruns
without also specifying a start-of burst timestamp. Often, test_messages
would report that no ACK was received, but instead, an underrun was
received.
test_messages also doesn't need to send three packets. The three packets
came from the "start of burst" flag, which no device in UHD supports.
The change is thus to send a single packet with an EOB marker for the
burst ACK test. This will work regardless of the link speed and CPU
power.
Note: Replacing everything with a lambda would be even better, but that
can't be easily scripted so we'll do this as a first step to reduce the
Boost footprint.
This also removes occurences of #include <boost/bind.hpp>, and makes
sure all usages of std::bind have an #include <functional>. clang-format
wasn't always applied to minimize the changeset in this commit, however,
it was applied to the blocks of #includes.
Due to conflicts with other Boost libraries, the placeholders _1, _2,
etc. could not be directly used, but had to be explicitly called out
(as std::placeholders::_1, etc.). This makes the use of std::bind even
uglier, which serves as another reminder that using std::bind (and even
more so, boost::bind) should be avoided.
nirio/rpc/rpc_client.cpp still contains a reference to boost::bind. It
was not possible to remove it by simply doing a search and replace, so
it will be removed in a separate commit.
rfnoc_nullsource_ce_rx, rfnoc_rx_to_file:
These examples are modified so they can be run with the new RFNoC API.
test_messages:
Fixes failures in the time test when it is executed immediately after an
underrun test. The DUC considers time specs on a per burst basis, so
when the underrun test leaves a burst unfinished, a time spec on the
next burst is ignored.
Remove UHD call to elevate thread priority to realtime. Setting all
threads to the same realtime priority can cause the threads to not share
access to the network interface fairly, which adversely affects
operation of the worker threads in UHD.
Turning off clang formatting around the program option declarations.
clang-format makes them looks bad an unreadable because it thinks the
options are function calls or something.
* The transmit streamer gives access to the async msg queue.
* The receive streamer gives access to the issue stream cmd.
* Supporting usrp implementation files updated.
* Example applications updated to use this API.
Renamed the example to test_messages (not just async).
Fixed bug in super recv packet handler related to messages.
Basically, the sequence number for messages should be ignored.
Fixed some quirks with usrp1 soft time control to get it work as well.
